水压爆破技术在隧道施工中的应用

Application of Hydraulic Blasting Technique in Tunnel Construction

随着我国基础设施建设工作的全面展开,对原有老旧建筑物和不合乎新时代要求的建筑物进行爆破是工作中的一项重要内容,同样在修筑道路桥梁时遇到隧道工程也需要爆破工作。在我国的隧道工程中,从"湿法"钻孔到"干法"钻孔,从非电起爆到火爆和电爆,爆破技术迎来了第三次大发展,即水压爆破技术。分析水压爆破技术的基本原理、操作方法和实施效果,并用实例重点介绍水压爆破技术在隧道施工中的应用。

With the work of our country＇s infrastructure construction in full swing, the original old buildings and does not conform to the requirements of the new era of building blasting is an important part of the work, the same in the construction of roads and bridges encountered tunnel project also required the demolition work.In the tunnel engineering of our country, from the ＂wet＂ drilling to the ＂dry＂ drilling, from the non electric initiation to the popular and electrical explosion, blasting technology ushered in the third major development, namely, hydraulic blasting technology.This paper analyses the basic principle, operation method and effect of hydraulic blasting technology.In this paper, the application of hydraulic blastinu technology in tunnel construction is introduced.
